Directional TSDF: Modeling Surface Orientation for Coherent …

Webconstructed TSDF structure, virtual camera views can be rendered from an arbitrary camera pose – the virtual camera can ray-cast the TSDF structure to identify the estimative surface points. Speciﬁcal-ly, the zero-crossing region is identiﬁed via a fast search procedure and the estimative surface points are interpolated within the zero- fixing company
